This invention relates to a track torpedo similar device, and ismore particularly con cerned "with the arrangement of a torpedo, which may preferably be of the loose loading type, in which the outstanding characteristics of assembling'a track torpedo.

are neatness, cheapness of construction, and elimlnatlon of machinery processes; Broad ly, the invention is exemplified in a container I of any suitable material, such as paper,hous-- ing a powder charge; which, in thepreferred instance isloosely packed, but which may be .of a more solid form compacted with any conventional form of binder; This2 powder. container, which is usually suitably water proofed, but'which is not necessarily so;'is wrapped in asuitable water-proofed covering such as water-proof paper or the like.

a A feature'ofithe invention is that the powder containermaybecut to such dimensions, that to secure the proper charge, it is powder, without definitely measuring the charge in any other manner. An outer j acket or strip of material, substantially of the rorm illustrated in the accompanying drawlngs,

' is employed to retain the torpedo package formed in the above described mannenx- The torpedo package is laid on this 'strip'of material, preferably with its longitudinal axis 'extending along the center line of-the iears of the piece of material. A strap of. metal such as lead, spring-steel or'thelikefis employed to secure the torpedo to the jacketbymeans of a suitable adhesive or the like. [The ears of the jacket a'rethen'folded about, the track torpedo, a'i'terwhich theendiof the jacket to which the strap isadhered lSI OllGd: end

over end to secure the package and the strap in a closely assembled relation. 7 The opposite end of the jacket,"ifdesired, may have an adhesive applied thereto, Whereby. itvmay be secured to the body of the torpedo.

An object of the invntiomftherefdre, is

to produce a track torpedo of newand-novel construction. 1 7

Another object is to produce a track torpedo characterized by its neatness, cheapness of construction, and elimination of machinery processes'during its construction.

I Another objectis; to produce a tracktorin'its extended position; a t I I c Fig. ,3 shows the nexttwo steps ofthe as I contain a suitable charge 2. This charge pedo employing a*container of such construe I tion that the necessary charge may be determined by merelyfilling the containerwith v powder;

. Anotherobject is to devise a novel. method.

Still another objectisto producea new- I form of acket or piece of material for-retain form of my invention Fig. 1 a perspect vev ew illustrating the {powdercont'ainer associated with its accompanying charge located upon its protective stripof material which, when in its as-.

sembled relation, produces the torpedo package illustrated in Fig. 2;

jFig. 2 is a; perspective View illustrating f the torpedo package of Fig. l,-properly located upon aretaining jacket which is shown semblage, wherein the ears of Fig. 2 have been folded over and about the torpedo package,

and therail-secured metallic strap is secured to oneend'ofthejackety v f r Fig; his a view similar to Fig. 8, but 'illu-strating the first rotation of the jacket end over end to produce the result illustrated in Fig. 5, while :iFig. 5 shows'the completed torpedo with the metallicstrap in its'extended position,

theend-of the jacket remote from the metal strap being secured to the adjacent turn of the" jacket by means of suitable adhesive or the likeii- Y. 0 rAt 1 is illustrated a container which may may preferablycomprise loosely packed powder, but may be of a more solid form compacted with any conventional form of binder. An advantage resident in the use of this form of container resides in the fact that if the container has a properly selected volume, it is necessary merely to loosely fill it with the charge, whereby the proper quantity of powder maybe determined without the necessity of any other method of measuring. As

- shown, the container with its powder charge is placed on a sheet of paper or thelike 3, preferably vwater-proofed in suitable manner, and being of substantially rectangular shape. This wrapping 3 is folded about the container in such manner as to produce thetorpedo' package indicated at 4 inFig. 2. The package thus assembled is then placed on asheet of material 5 such as water-proofed paper or thelike, preferably of rectangular shape, but having ears 6' and 7 formed along the longitudinal edges thereof. These ears preferably have the form of truncated triangles, the bases of which are substantially the same length as the longitudinal sides of the rectangular portion. As shown, the edge 8 of the jacketportiont may be ofa slightly greater Width than the opposite end 9, though j this particular construction need notbe folas a suitable adhesive 15 or the like. edge 8 is thenrolled over' as indicated in Fig.

lowed necessarily. The outermost portions lO'and 11 of the ears 6 and 7 are" then folded over upon the package 4 substantially in the manner indicated in Fig. 3, and the portions 10 and 11 are preferably slightly c'rimped.

7 During the folding proc'ess,the entire extent of the ears, 6 and 7 are preferably folded over upon the rectangular mid-portion, substantially. along the lines indicated at 12 and 13. Aethi'stime, a strip of'lead, spring-steel,

or other suitable material, indicated at 14,.

and preferably of relatively great length as compared to its width, is placed on the jacket 5 adjacent the end 8 thereof, and in the preferred form is secured thereto by means 4, and this wrapping process, end over end, is continued until the package, similar to that -illustrated'in Fig. 5, is produced. At this from one of the transverse edges thereof, and

is located substantially midway between the longitudinal extremities. The longitudinal edges of the jacket adjacent the extremities of the powder container are then crimped up over the container, and with the crimps held in position by the operators fingers, the jacket is then folded about the container, beginning at the one end, for approximately one turn. -The metal strap 14 is then preferably sealed to the exterio'r of the jacket adjacent the before-mentioned turn thereof, after which the rolling process is continued for approximately two or three additional turns.

The outer end ofthe jacket is then dipped in any suitable binder, after which it is adapted to seal the whole torpedo together, holding all the apparatus in its relative position, and

resulting in a thoroughly water-proof torpedo, It is contemplated, however, that if desirable, the jacket 5 shall be coated on its interior surface with a suitable adhesive, so that it is merely necessary to moisten the same to cause it to adhere firmly to the torpedo package and the strap. I

With the strip assembled in the manner indicated in Fig. 5, it is necessary only to shape the strap 14 to the head of the rail in order to place the torpedo in its operable position. The torpedo so produced is characterized by its safety and efficiency as a signal, simplicity and neatness of appearance, together with its extremely great strength, resulting from the constructional process employed. It is of course understood, that the jacket 3 may be omitted if desired and that numerous modifications can be made in the preferred process, without departing from the spirit of the invention. Accordingly, it is intended that the invention be limited only by the scope of the appended claims.
